Description
AI Translation Available
FFmpeg through 9.0.2 contains a denial of service vulnerability in the DASH demuxer that allows attackers to trigger an infinite loop by supplying an empty SegmentTemplate media URL. Attackers can craft an .mpd manifest declaring SegmentTemplate media='' so get_current_fragment() calls av_strireplace() with an empty search string, consuming CPU indefinitely.
